TECHNICAL FIELD

The present invention relates to indole compounds, compositions, and uses thereof, including uses of the indole compounds and compositions for the reduction or removal of localized fat deposits and/or tightening of skin and soft tissue laxity in subjects. The indole compounds can be employed, for example, in the cosmetic sector or for producing pharmaceutical products.

BACKGROUND

Liposuction is one of the most popular cosmetic surgery procedures currently available. It involves the surgical removal of fat deposits using suction, optionally assisted by solutions to assist in fat removal. Liposuction, also known as lipoplasty or suction lipectomy, reduces fat through an incision in the skin through which a cannula is inserted. Tumescent fluid is injected into the treatment region, then the cannula is inserted. The cannula is connected to a suction source and the unwanted fat is aspirated through the cannula and discarded. Liposuction is performed under general or local anesthesia, depending on the amount and location of the fat to be reduced.

The use of liposuction and/or other surgical methods of fat removal are associated with significant adverse events including temporary bruising, swelling, numbness or hypersensitivity, soreness and burning sensation, risk of infection, and pigmentation changes. Other more serious complications include the formation of fat clots or blood clots, which can migrate to the lungs and cause death; excessive fluid loss, which can lead to shock; fluid accumulation that must be drained; fluid overload leading to congestive heart failure; friction burns or other damage to the skin or nerves; and perforation injury to the vital organs. Additionally, liposuction requires a recovery time of up to 1-2 weeks. Moreover, because surgical procedures such as liposuction require local and occasionally general anesthesia, significant anesthesia-related risks are associated with surgical fat removal.

In 1959, phosphatidylcholine (hereinafter “PC”) was isolated and used intravenously in Odessa, Russia, for the treatment of fat embolism. PC has also been used in treating xanthelasmas in Europe and in South America. An injectable form of PC (LIPOSTABIL®, Sanofi-Aventis, Brigewater, N.J.) has been indicated for treatment of fat embolisms, coronary artery plaque, and fat tissue.

PC is often an ingredient in injectable fat reducing formulas. When isolated, it is produced as a powder. When reconstituted, it is quite viscous and must be mixed with a detergent, such as sodium deoxycholate (hereinafter “DC”), to solubilize it sufficiently to create an injectable form. DC is a bile salt that can function to make the PC soluble in water or other biocompatible solvents; otherwise, the PC can precipitate out of solution. DC has been described as having a “detergent” effect on fat dissolution in a porcine in vitro study and has nonspecific effects on both adipose and muscle cells. Other pharmaceuticals, such as FUNGIZONE® (Bristol Myers Squibb, New York, N.Y.) (an injectable form of amphotericin B), are commonly combined with bile salts to enhance their solubility and make them compatible with intravenous delivery.

While formulations of DC without PC (“DC formulations”) and formulations of PC combined with DC (“PC/DC formulations”) have been shown to achieve a level of fat reduction, substantial unresolved problems remain with the use of such formulations and methods of use, as reported in Duncan et al. (Duncan D. Injection lipolysis for body contouring, p 59-70. Body Contouring, ed. Schiffman and DiGiuseppe, Springer 2010, Berlin.).

While meeting with some success, prior techniques and compositions have met with certain limitations, such as skin loss, drainage of liquefied necrotic fat, excessive fibrosis, injections into muscle causing weakness, nodules, or adhesions with limitation of range of motion, numbness, paresthesias, and marginal mandibular nerve palsy. Therefore it would be desirable to have a method of reducing localized fat deposits that does not require surgery or prolonged recovery time and has fewer adverse side effects than currently available methods.

When a fully unsaturated carbocyclic ring satisfies Huckel's rule, then the ring is also called an “aromatic ring”. “Saturated carbocyclic” refers to a ring having a backbone consisting of carbon atoms linked to one another by single bonds; unless otherwise specified, the remaining carbon valences are occupied by hydrogen atoms.

“Heteroaryl” refers to an aromatic group of from 1 to 15 carbon atoms, such as from 1 to 10 carbon atoms and 1 to 10 heteroatoms selected from the group consisting of oxygen, nitrogen, and sulfur within the ring. Such heteroaryl groups can have a single ring (such as, pyridinyl, imidazolyl or furyl) or multiple condensed rings in a ring system (for example as in groups such as, indolizinyl, quinolinyl, benzofuran, benzimidazolyl or benzothienyl), wherein at least one ring within the ring system is aromatic and at least one ring within the ring system is aromatic, provided that the point of attachment is through an atom of an aromatic ring. In certain embodiments, the nitrogen and/or sulfur ring atom(s) of the heteroaryl group are optionally oxidized to provide for the N-oxide (N→O), sulfinyl, or sulfonyl moieties. This term includes, by way of example, benzimidazolyl, pyridinyl, pyrrolyl, indolyl, thiophenyl, and furanyl. Unless otherwise constrained by the definition for the heteroaryl substituent, such heteroaryl groups can be optionally substituted with 1 to 5 substituents, or from 1 to 3 substituents, selected from acyloxy, hydroxy, thiol, acyl, alkyl, alkoxy, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, substituted alkyl, substituted alkoxy, substituted alkenyl, substituted alkynyl, substituted cycloalkyl, substituted cycloalkenyl, amino, substituted amino, aminoacyl, acylamino, alkaryl, aryl, aryloxy, azido, carboxyl, carboxyl ester, cyano, halogen, nitro, heteroaryl, heteroaryloxy, heterocyclyl, heterocyclooxy, aminoacyloxy, oxyacylamino, thioalkoxy, substituted thioalkoxy, thioaryloxy, thioheteroaryloxy, sulfonylamino, —SO-alkyl, —SO-substituted alkyl, —SO-aryl, —SO-heteroaryl, —SO₂-alkyl, —SO₂-substituted alkyl, —SO₂-aryl and —SO₂-heteroaryl, and trihalomethyl.

Examples of heteroaryls include, but are not limited to, benzimidazole, pyrrole, imidazole, pyrazole, pyridine, pyrazine, pyrimidine, pyridazine, indolizine, isoindole, indole, purine, isoquinoline, quinoline, phthalazine, naphthylpyridine, quinoxaline, quinazoline, cinnoline, pteridine, carbazole, carboline, phenanthridine, acridine, phenanthroline, isothiazole, phenazine, isoxazole, phenoxazine, phenothiazine, piperidine, piperazine, phthalimide, 4,5,6,7-tetrahydrobenzo[b]thiophene, thiazole, thiophene, benzo[b]thiophene, and the like.

“Heterocycle,” “heterocyclic,” “heterocycloalkyl” or “heterocyclyl” refers to a saturated or partially unsaturated group having a single ring or multiple condensed rings, including fused, bridged, or spiro ring systems, and having from 3 to 20 ring atoms, including 1 to 10 hetero atoms. These ring atoms are selected from the group consisting of carbon, nitrogen, sulfur, or oxygen, wherein, in fused ring systems, one or more of the rings can be cycloalkyl, aryl, or heteroaryl, provided that the point of attachment is through the non-aromatic ring. In certain embodiments, the nitrogen and/or sulfur atom(s) of the heterocyclic group are optionally oxidized to provide for N-oxide, —S(O)—, or —SO₂— moieties.

Examples of heterocycles include, but are not limited to, azetidine, dihydroindole, indazole, quinolizine, imidazolidine, imidazoline, piperidine, piperazine, indoline, 1,2,3,4-tetrahydroisoquinoline, thiazolidine, morpholinyl, thiomorpholinyl (also referred to as thiamorpholinyl), 1,1-dioxothiomorpholinyl, piperidinyl, pyrrolidine, tetrahydrofuranyl, and the like.

Where a heteroaryl or heterocyclyl group is “substituted,” unless otherwise constrained by the definition for the heteroaryl or heterocyclic substituent, such heteroaryl or heterocyclic groups can be substituted with 1 to 5, or from 1 to 3 substituents, selected from alkyl, substituted alkyl, alkoxy, substituted alkoxy, cycloalkyl, substituted cycloalkyl, cycloalkenyl, substituted cycloalkenyl, acyl, acylamino, acyloxy, amino, substituted amino, aminoacyl, aminoacyloxy, azido, cyano, halogen, hydroxyl, oxo, thioketo, carboxyl, carboxyl ester, thioaryloxy, thioheteroaryloxy, thioheterocyclooxy, thiol, thioalkoxy, substituted thioalkoxy, aryl, aryloxy, heteroaryl, heteroaryloxy, heterocyclyl, heterocyclooxy, hydroxyamino, alkoxyamino, nitro, sulfonylamino, —SO-alkyl, —SO-substituted alkyl, —SO-aryl, —SO-heteroaryl, —SO-heterocyclyl, —SO₂-alkyl, —SO₂-substituted alkyl, —SO₂-aryl, —SO₂-heteroaryl, and —SO₂-heterocyclyl.

The term “substituted,” when used to modify a specified group or radical, can mean that one or more hydrogen atoms of the specified group or radical are each, independently of one another, replaced with the same or different substituent groups.

In a certain embodiment, a group that is substituted has 1, 2, 3, or 4 substituents, 1, 2, or 3 substituents, 1 or 2 substituents, or 1 substituent.

It is understood that in all substituted groups defined above, compounds arrived at by defining substituents with further substituents to themselves (e.g., substituted aryl having a substituted aryl group as a substituent which is itself substituted with a substituted aryl group, which is further substituted by a substituted aryl group, etc.) are not intended for inclusion herein. In such cases, the maximum number of such substitutions is three. For example, serial substitutions of substituted aryl groups specifically contemplated herein are limited to substituted aryl-(substituted aryl)-substituted aryl.

Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “arylalkyloxycarbonyl” refers to the group (aryl)-(alkyl)-O—C(O)—.

As to any of the groups disclosed herein which contain one or more substituents, it is understood, of course, that such groups do not contain any substitution or substitution patterns which are sterically impractical and/or synthetically non-feasible. In addition, the subject compounds include all stereochemical isomers arising from the substitution of these compounds.

The term “pharmaceutically acceptable salt” means a salt which is acceptable for administration to a subject, such as a mammal (salts with counterions having acceptable mammalian safety for a given dosage regime). Such salts can be derived from pharmaceutically acceptable inorganic or organic bases and from pharmaceutically acceptable inorganic or organic acids. “Pharmaceutically acceptable salt” refers to pharmaceutically acceptable salts of a compound, which salts are derived from a variety of organic and inorganic counter ions well known in the art and include, by way of example only, sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium, and the like; and when the molecule contains a basic functionality, salts of organic or inorganic acids, such as hydrochloride, hydrobromide, formate, tartrate, besylate, mesylate, acetate, maleate, oxalate, and the like.

The term “salt thereof” means a compound formed when a proton of an acid is replaced by a cation, such as a metal cation or an organic cation and the like. Where applicable, the salt is a pharmaceutically acceptable salt, although this is not required for salts of intermediate compounds that are not intended for administration to the subject. By way of example, salts of the present compounds include those wherein the compound is protonated by an inorganic or organic acid to form a cation, with the conjugate base of the inorganic or organic acid as the anionic component of the salt.

“Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water. When the solvent is water, the solvate formed is a hydrate.

“Tautomer” refers to alternate forms of a molecule that differ only in electronic bonding of atoms and/or in the position of a proton, such as enol-keto and imine-enamine tautomers, or the tautomeric forms of heteroaryl groups containing a —N═C(H)—NH-ring atom arrangement, such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles. A person of ordinary skill in the art would recognize that other tautomeric ring atom arrangements are possible.

It will be appreciated that the term “or a salt or solvate or stereoisomer thereof” is intended to include all permutations of salts, solvates and stereoisomers, such as a solvate of a pharmaceutically acceptable salt of a stereoisomer of subject compound.

As used herein, an “effective dosage” or “effective amount” of drug, compound, or pharmaceutical composition is an amount sufficient to effect beneficial or desired results. An effective dosage can be administered in one or more administrations. As is understood in the clinical context, an effective dosage of a drug, compound, or pharmaceutical composition may or may not be achieved in conjunction with another drug, compound, or pharmaceutical composition. Thus, an “effective dosage” may be considered in the context of administering one or more therapeutic agents, and a single agent may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable result may be or is achieved.

As used herein, “in conjunction with” refers to administration of one treatment modality in addition to another treatment modality. As such, “in conjunction with” refers to administration of one treatment modality before, during or after administration of the other treatment modality to the individual.

An “individual” or a “subject” is a mammal, more preferably a human. Mammals also include, but are not limited to, farm animals, sport animals, pets (such as cats, dogs, horses), primates, mice and rats.

As used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly indicates otherwise.

Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X.”

It is understood that aspect and variations of the invention described herein include “consisting” and/or “consisting essentially of” aspects and variations.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, the preferred methods and materials are now described.

The nomenclature used herein to name the subject compounds is illustrated in the Examples herein. This nomenclature has generally been derived using the commercially-available AutoNom software (MDL, San Leandro, Calif.).

It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination. All combinations of the embodiments pertaining to the chemical groups represented by the variables are specifically embraced by the present invention and are disclosed herein just as if each and every combination was individually and explicitly disclosed, to the extent that such combinations embrace compounds that are stable compounds (i.e., compounds that can be isolated, characterized, and tested for biological activity).

DETAILED DESCRIPTION

The present invention provides methods and lypolytic indole compounds for reducing fat and/or tightening skin and lax soft tissue. Tissue specificity is an important consideration for developing lipolytic agents. Compounds that are not tissue-specific may have significant effect on neighboring tissues, for example necrosis of blood vessels, eccrine, glands, the reticular layer of the dermis, and demyelination of peripheral nerves, leading to side effects such as skin loss, itching, numbness, paresthesia, or even mandibular nerve palsy. It was surprisingly found that indole-based compounds are effective in killing adipocytes selectively and while in the meantime less toxic to muscle cells, nerve cells, and dermal cells. These compounds are therefore particularly suitable for fat reduction in vivo.

It was further surprisingly found that these indole compounds may have specific functional profiles in terms of potency, cell specificity, and cell killing characteristics (for example apoptotic, cytolytic, and/or pyroptotic), and that such functional profiles make them particularly suitable for fat reduction, skin and soft tissue tightening, and/or other applications discussed herein. A tailored treatment can therefore be developed depending on the amount of fat to be removed, the amount of anticipated post-treatment tissue laxity or firmness, as well as the effect on the skin surface area.

For example, in some embodiments, the indole compounds are apoptotic and non-inflammatory. It was previously shown that injection of currently available lipolysis drugs, such as deoxycholate or phosphatidylcholine combined with deoxycholate, produce significant side effects such as prominent and immediate swelling, bruising, pain, and inflammation. Fat-reducing injections that cause little or no swelling, bruising, or pain would therefore be particularly advantageous in many instances and would allow patients undergo more than one treatments in the desired region without severe sequelae. Examples of such desirable treatment regions include, for example, abdomen, thighs, flanks, and any other regions with significant adiposity.

In some embodiments, the indole compounds are cytolytic and inflammatory. The cytolytic effect, i.e., cell membrane rupture in soft tissue is most likely to cause significant inflammation. While this mechanism may lead to swelling and possibly bruising, the inflammation may lead to soft tissue tightening, skin surface area reduction, and the production of tissue firmness in the case of previous laxity. This is particularly useful when removing fat in areas involving skin laxity. For example, the degree of pendulous overhang of a region (such as a jowl or a “bat wing” of the arm) can be improved. An area which previously drooped below a normal axis can be lifted, with restoration of a normal contour.

In some embodiments, the indole compounds are pyroptotic, i.e., having a combined effect of apoptosis and cytolysis. Such compounds are particularly useful when both fat reduction and improvement and skin laxity are desirable.

Thus, the present invention in one aspect provides compositions suitable for reducing or removing localized fat deposits and/or tightening skin. In another aspect, there are provided methods for reducing or removing localized fat deposit and/or tightening skin. Also provided are kits, unit doses, and articles of manufacture useful for methods described herein.

Adipose tissue (or body fat, or fat deposit, or fat) is loose connective tissue containing adipocytes. Adipose tissue can be found, for example, at the skin (subcutaneous fat), around internal organs (visceral fat), in bone marrow (yellow bone marrow) and in breast tissue. The present methods can be used for reducing fat deposit in any of these adipose tissues. The fat to be reduced or removed can be of varying hardness, depending on its contents. In certain embodiments, the fat deposit is soft fat. In certain embodiments, the fat deposit is fibrotic fat. While adipocytes are one component of the fatty layer, there are many different cell types in the hypodermis. About 18% of these cells are adipocytes. There is also a fibroseptal network—the collagenous framework in which the adipocytes reside. This layer is also known as the stromal vascular fraction. The present methods can be used for reducing the fibroseptal network.

The compositions and methods can be used to treat any adipose condition in a subject. Adipose conditions include, for example, disorders such as metabolic syndrome, obesity, fat redistribution syndrome, eyelid fat herniation, lipoma, herniation, cellulite, lipodystrophy (including buffalo hump lipodystrophy), dorsocervical fat, visceral adiposity, breast enlargement, hyperadiposity, diffused body fat around trunk and arms, fat deposits associated with cellulite, Dercum's disease, Madelung's neck, lipedema, piezogenic nodules, Launois Cleret syndrome, and xanthelasma.

In some embodiments, there is provided a method for treating an adipose tissue disorder or an adipose tissue tumor in a subject comprising locally administering to the subject a composition comprising compound 44. In some embodiments, the method is for cosmetic purposes.

Adipose tissue disorders include, for example, disorders such as metabolic syndrome, familial lipomatosis, lipoma, Dercum's disease, Madelung's neck, lipedema, piezogenic nodule, xanthelasma, lipodystrophy, and cellulite. Adipose tissue disorders show, in contrast to the food-related obesity-correlated lipohypertrophy, tissue conditions or identities which can be pathologically differentiated unambiguously and which can be described by histological parameters of scarring and inflammation, but also by connective tissue encapsulations and by changes in the histological adipose tissue morphology itself.

A lipoma is an adipose tissue tumor, which is benign, slow-growing, usually spherical, possibly pedunculated (=I. pendulum) or even villous (=I. arborescens, for example of the synovial villi) mesenchymal tumors composed of enlarged-adipose tissue cells, such as in a subcutaneous cell tissue, possibly with central ossification (=I. ossificans), becoming mucoid (=I. myxomatodes) or calcifying (=I. petrificans), also with increased connective tissue and capsule formation (=I. fibrosum), neoangiogenesis (=I. teleangiectodes), rarely showing malignant degeneration (=I. sarcomatodes, liposarcoma). A lipoma can be categorized as pathological because they grow and their connective tissue envelope may be painful per se, as well as the compression derived therefrom on blood vessels, which may cause neuralgia.

In some embodiments, the compositions can be used to treat an adipose condition, adipose tissue disorder, lipodystrophy, or adipose tissue tumor in various areas of a subject. For example, the compositions can be used to reduce or remove fat deposits localized under the eyes, in the lower face and jowls, under chin, under arm, buttock, calf, back, thigh, ankle, stomach, cheek, brow, “love-handles”, ankles, lips, or trachea of a subject. In some embodiments, the compositions can be used to treat omental adipocyte hypertrophy. In some embodiments, areas of laxity with adjacent fat can be treated, such as the vagina, urethra, and uvula, with the compositions.

The total volume, unit dose and number of treatments administered may vary depending on the amount of fat in a target site, the location of the target site, type of fat composition, the degree of tissue laxity, and desired results. In general, the greater the amount of fat being treated, the greater the dose that is administered. The type of compound used will depend on the relative degree of fatty hypertrophy versus tissue laxity. The compositions and unit dosages herein may be administered to a subject as part of a treatment regimen or as an individual treatment session.

In some embodiments according to any one of the methods described herein, the method further includes a step of ascertaining the effectiveness of the method. In some embodiments, the effectiveness is determined by a physical measurement, such as MRI, high resolution ultrasound, or caliper. In some embodiments, the localized fat is reduced by at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% of the volume, or by at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% of its thickness, as determined by MRI or by caliper measurement. The % of the volume reduction can be determined by subtracting the volume after treatment (volume after treatment: Vf) and that of the baseline (initial volume or volume before treatment: Vi), divided by Vi and multiplied by 100. Similarly the % of the thickness reduction can be determined by subtracting the thickness after treatment (thickness after treatment: TO and that of the baseline (initial volume or volume before treatment: Ti), divided by Ti and multiplied by 100. As an example to determine percentage reduction in volume, if Vi is 6346.8 cc, Vf is 5376.6 cc, then the volume is reduced by 18%. Similarly to determine percentage reduction in thickness, if Ti is 17.2 mm, Tf is 14.1 mm, then the thickness is reduced by 15%.

In some embodiments, the submental fat deposit treated by the methods of the present disclosure is cosmetically unappealing but is non-pathological and the reduction of it is to improve the appearance of the subject. In certain embodiments, the result is reduction of the appearance of a double chin. In some embodiments, the method is non-surgical and does not include liposuction.

In some embodiments, the method can further include a step of ascertaining the effectiveness of the method. In some embodiments, the effectiveness is determined by a physical measurement, such as MRI, high resolution ultrasound, or caliper. A thickness and/or volume of the submental fat deposit can be measured with magnetic resonance imaging (MRI), high resolution ultrasound, or by a caliper. The thicknesses and/or volumes of the submental fat deposit can be compared before and after the treatment to assess the effectiveness of the treatment. In some embodiments, the thickness and/or volume is reduced by at least about 10%, or by at least about 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50%.

The reduction of submental fat can enhance the facial appearance of said subject. In some embodiments, the enhanced facial appearance is due to the reduction of prominence of a double chin. In some embodiments, the effectiveness of the treatment can be assessed by visual inspection for a reduction of prominence of a double chin or lack of a double chin. The lessening of the double chin appearance may be determined by the improvement in the degree of the submental convexity of the area under the chin.

The methods described herein, in some embodiments, are useful for one or more of the following: 1) rejuvenating skin; 2) skin and subcutaneous tissue tightening; 3) causing skin and soft tissue retraction in a body region containing fat deposits, such as localized fat, cellulite, or a postlipoplasty deformity; 4) alleviating skin conditions, including cellulite, rippling, divots (skin contour irregularities following lipoplasty), and protuberances; 5) removing localized excess skin; and/or 6) firming the skin and soft tissue.

In some embodiments, the compositions are administered locally to a target area to create an inflammatory response causing subcutaneous collagen deposition with subsequent soft tissue retraction. The formation of a scar results in skin and soft tissue tightening especially in areas where the skin is under little or no tension and provides little resistance to fibroseptal contraction. Such treatment may be relevant in a number of clinical scenarios such as, for example, commonly performed fat treatments, including, but not limited to, large volume liposuction. The latter may be associated with post-liposuction, or weight loss induced skin and soft tissue laxity. Thus, in some embodiments, a composition comprising a therapeutically effective amount of an indole compound may be administered to a liposuction site after completion of the liposuction procedure. In some embodiments, the indole compound is a compound of Formula (I). In some embodiments, the method comprises administering a compound of any one of Formula (II), (III), (IV), (V) and (VI) or any one of Compounds 2, 10, 29, 38, 40, 41, 43, and 44.

In some embodiments, the target area is an area under eye, under chin, under arm, buttock, calf, back, thigh, stomach, cheek, brow, or any other skin regions showing aging, wrinkles, loose skin or skin irregularity.

In some embodiments, the method can further include a step of ascertaining the effectiveness of the method. The present disclosure also provides a method for ascertaining the effectiveness of a therapy for preventing or reducing a skin condition associated with aging in a subject, comprising comparing the skin condition of the subject before therapy with the skin condition of the subject after therapy, wherein smooth skin retraction without rippling, crease, or local indentation in the subject after therapy indicates effective therapy. The comparison can be done by visual inspection or patient satisfaction surveys. Other methods of ascertaining the effectiveness of the method include high resolution ultrasound, MRI dermatological wrinkle scale, Canfield Vectra 3D® imaging system, and calipers. High resolution ultrasound can be used to measure the thickness of a fatty deposit at certain sites. MRI is currently the “gold standard” in measuring the depth and width of subcutaneous fat deposits in a given region. Canfield Vectra 3D® imaging system is a mathematical way of determine smoothness of skin. The system uses a quadratic equation to determine positive and negative variations to form a computer-generated ideal of smooth curved surface for a given photographed region. The “smoothness index” is a way to measure the pre-treatment variation from the ideal surface. After treatment, another 3D photo is taken. The treatment region is identified, and the equation can be used to determine the change/improvement in surface contour irregularity.

In some embodiments, there is provided a method for a method for treating obstructive sleep apnea comprising locally administering to the subject a composition comprising compound 44. Obstructive sleep apnea is characterized by repetitive pauses in breathing during sleep due to the obstruction and/or collapse of an upper airway (throat), usually accompanied by a reduction in blood oxygen saturation, and followed by an awakening to breathe. It is a dangerous (sometimes life threatening) condition that often affects obese people. Obese people have a large amount of fat around their trachea, and this fat may cause their airway to collapse when their muscles relax during sleep. In some embodiments, the compositions are used to treat obstructive sleep apnea by reducing fat around the trachea. In such embodiments, the composition is administered locally (e.g., via injection) to a target site of fat around the trachea in a therapeutically effective amount.

In the above methods, in some embodiments, the subject being treated is a mammal. Such mammal can be a human or an animal such as a primate (e.g., a monkey, chimpanzee, etc.), a domesticated animal (e.g., a dog, cat, horse, etc.), farm animal (e.g., goat, sheep, pig, cattle, etc.), or laboratory animal (e.g., mouse, rat, etc.). In some embodiments, a subject being treated is a human, a horse, a dog, or a cat. In some embodiments, a subject can be a male or female human. A subject can be a human of any age, such as young age, adolescent age, adult age, middle age, or old age. In some embodiments, the subject can be an age of 1-4, 5-9, 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89, or 90-100 years.

In some embodiments, a subject is overweight or obese. In some embodiments, a subject is of normal weight or underweight. Overweight or obesity can be assessed, for example, by BMI (body mass index). A method for calculating BMI includes dividing a person's body weight in kilograms by their height in meters squared (weight [kg]/height [m]²). A BMI of 30 or more is considered obese; a BMI between 25 to 29.9 is considered overweight; a BMI between 18.5 to 24.9 is considered normal weight; a BMI under 18.5 is considered underweight. In some embodiments, a subject has a BMI over about 30, such as about 30 to about 50. In some embodiments, a subject has a BMI of about 25 to about 29.9. In some embodiments, a subject has a BMI under about 25.

In some embodiments, the subject has a fat deposit. In some embodiments, the subject has skin and soft tissue laxity. In some embodiments, the subject has a fat deposit and skin and soft tissue laxity.

A “target site’ used herein refers to an area of the body at which the composition is applied. The target site can be located at the fat deposit and/or the skin area to be affected. The target site can be at different levels of the skin, such as epidermis, dermis, or hypodermis. The target site can be intradermal (within or between layers of skin).

In some embodiments, the compound is administered locally. “Local administration” used herein refers to administration of a substance to an area where the action of the substance is desired. Sometimes, administration of the substance is directly to the area where the action of the substance is desired. In some embodiments, the compositions are administered via a localized injection. However, other means of administering the compositions are also contemplated. For example, the compositions may be administered via a transdermal pump, a transdermal patch, or a subdermal depot. In some embodiments, the compositions are administered topically.

In some embodiments, the composition is administered transdermally or subcutaneously, via e.g., a subcutaneous injection using a syringe to a target site. In some embodiments, the composition is administered by injection at hypodermis level, injection into the superficial level to mid-layer of subcutaneous fat, mid-layer or deep layer of subcutaneous fat, or injection into the lipodystrophic region. The compositions may be administered at the same, adjacent, or nearby target sites at various intervals, dosages, volumes, as disclosed herein.

In some embodiments, a target site can be, for example, 0.1 cm×0.1 cm, to about 5 cm×5 cm before the procedure. In some embodiments, the target site can be 0.1 cm×0.1 cm, 0.5 cm×0.5 cm, 1 cm×1 cm, 2 cm×2 cm, 3 cm×3 cm, 4 cm×4 cm, or 5 cm×5 cm.

The compositions may be administered once or multiple times into the target site. In some embodiments, the compositions are administered at least 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 times to a target site. More than one administration can occur in a single week, month, year, 2-5 years, or 5-10 years. In some embodiments, the subject is given 1-100, 2-50, 3-30, 4-20, or 5-10 injections at a target site. This number of injections can occur over a period of 1 week, 2 weeks, 3 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, 1 year, 2 years, 3 years, 4 years, 5 years, 6 years, 7 years, 8 years, 9 years, or 10 years. In some embodiments, the compositions are administered weekly or 1-8 weeks apart.

In some embodiments, the subject is given 1 to 10 injections with intervals of 1 to 12 weeks; or 2 to 8 injections with intervals of 2 to 10 weeks; or 2 to 6 injections with intervals of 2 to 8 weeks. In some embodiments, the subject is given 2 to 4 injections with intervals of 4 to 8 weeks.

The compositions can be administered at various levels below the dermis. In some embodiments, the compositions can be administered with a 2-15 mm injection depth. In some embodiments, the injection depth is 2-4, 4-6, 6-8, 8-10, 10-12, or 12-15 mm. In some embodiments, the injection depth is 4-10, 6-10, 2-8, or 6-8 mm.

The compositions can be administered anywhere within the fatty layer. Because some of the compositions have certain dispersion when injected in a depot manner, in some embodiments, the compositions are administered with multilevel depots. For example, one administration could be immediately under the skin in the superficial hypodermis; and another administration could be halfway through the hypodermis; and another administration could be deep, just above the fascia. The present disclosure provides a multilevel injection approach, using needles of different lengths.

The dose can depend on the following factors—the amount of fat present, the desired effect desire, and the concentration of the drug. In some embodiments, a solution for injection comprises about 1-100 mg/ml of the indole composition. In some embodiments, a solution for injection comprises about 1-5, 6-10, 11-15, or 16-20 mg/ml of the indole composition. n some embodiments, a solution for injection comprises about 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, 81-90, or 91-100 mg/ml of the indole composition. In some embodiments, a solution for injection comprises about 8-12 or 10 mg/ml of the indole composition.

In some embodiments, the volume for each injection is about 0.1 ml to about 0.5 ml. In some embodiments, the total of an indole compound administered is between about 50 mg to about 100 mg, or from about 60 mg, 70 mg to about 90 mg, 80 mg, without limitation.

In some embodiments, the method comprises local injection to the target site, through a plurality of injection sites on the skin area, a composition comprising an effective amount of an indole compound, wherein the effective amount is from about 0.01 mg to about 10 mg per injection site. In some embodiments, the effective amount is at least about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 mg per injection site. In some embodiments, the effective amount if no more than about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 mg per injection site.

In some embodiments, the plurality of injection sites is substantially evenly distributed on the skin area. The term “substantially evenly” as used here, refers to injection sites in an area where there are substantially the same number of injection sites per unit of area. In one aspect, a number is substantially the same as another number is they are with about 5% or 10%, or 15% or 20%, or 25% difference.

In some embodiments, each injection site is from about 0.8 cm to about 1.2 cm distant from an adjacent injection site. In some embodiments, each injection site is from about 0.9 cm to about 1.1 cm distant from an adjacent injection site. In some embodiments, each injection site is about 1 cm distant from an adjacent injection site.

In some embodiments, the plurality of injection sites comprises at least 20 injection sites, or alternatively at least 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500 injection sites. In some embodiments, the plurality of injection sites has of no more than about 100, 90, 80, 70, 60, 50, 45, 40, 35, 30, or 25 injection sites. In some embodiments, the plurality of injection sites has from about 40 to about 60 injection sites, or about 50 injection sites.

In some embodiments, each injection site receives from about 0.1 ml to about 0.5 ml of the composition. In some embodiments, each injection site receives from about 0.1 ml to about 0.25 ml, or alternatively from about 0.26 to about 0.5, or from about 0.2 to about 0.4 ml of the composition.

In some embodiments, the method utilizes a grid comprising a plurality of injection sites, each of which is from about 0.8 cm to about 1.5 cm distant from an adjacent injection site of the grid; and injecting, with a suitable needle, through each of the plurality of injection sites, into about half way into the target site, an effective amount of a composition comprising from about 0.5% to about 1% (w/w) of an indole compound, wherein each injection constitutes delivery of from about 0.1 ml to about 0.3 ml of the composition.

In some embodiments, the grid comprises at least 20 injection sites, or at least 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90, or 100 injection sites. In some embodiments, the grid comprises no more than about 100, 90, 80, 70, 60, 50, 45, 40, 35, 30, or 25 injection sites. In some embodiments, the grid comprises from about 40 to about 60 injection sites, or about 50 injection sites.

An alternative pattern would be a multi-level injection, using an under-the-skin type delivery. These would be performed from a single entry site, and would be executed in a ray-type distribution, similar to liposuction. The value of treating multiple levels of adiposity has been recently shown, so a better and more uniform response can be obtained with this method. Also, drugs with poor dispersion can be better delivered to the target tissue this way.

In some embodiments, the method further comprises pretreating the area around the injection sites with a local anesthetic. Various anesthetics individually or in combination may be included in the composition such as: ropivacaine, articaine, benzocaine bupivacaine, chloroprocaine, etidocaine, hexylcaine, lontocaine, lidocatine, levobuivaciaine, mepivacaine, prilocaine, procaine, and tetracaine. In some embodiments, co-administration of an anesthetic either the composition can reduce the number of injections

In some embodiments, the indole compound is apoptotic. In some embodiments, the indole compound is cytolytic. In some embodiments, the indole compound is pyroptotic. Such properties can be determined, for example, through histology with fresh ex-vivo fat tissues. The presence of cell wall lysis, “ghosting,” and loss of integrity of regions of confluent adipocytes can indicate that an indole compound has activity against adipocytes. Signs of apoptosis, histologically, include “ghosting” and regions of shrinking or much smaller cells. Signs of cytolysis include disruption of cell walls, and with aggressive compositions and the detergent controls, large “moth-eaten” regions where no cells exist; they have all been lysed. Signs of pyroptosis include a combination of both findings. In a live animal or human, cytolysis can produce inflammatory changes.

In some embodiments, the indole compounds are inflammatory. In some embodiments, the indole compounds are non-inflammatory. In some embodiments, the indole compounds are moderately inflammatory. Depending on the mechanism of action, the level of inflammation induced by indole compounds varies. Inflammatory response is generated when the cell wall is mechanically lysed or the cell dies an ischemic death. Release of the cell contents and lysozymes triggers significant local swelling, and a cytokine and histamine response. An early indicator is the presence of neutrophils or lymphocytes in the affected target tissue. With an aggressive composition, large areas of viable cells are missing, and the region is filled with ground substance. Fibrosis is indicated by thickening of the fibrous septae. Macrophages infiltrate, and “crown-like” structures—noted by the presence of macrophages at the verge of an adipocyte cell wall-are also hallmarks of fatty inflammation. Cytolytic indoles can generate an inflammatory response. Apoptosis is noninflammatory. There are no macrophages, nor is there an apoptotic target. Apoptosis occurs when the cell is programmed to die. The cell shrinks and “ghosting—the residual intact cell wall without much cytoplasm—can be seen.

In some embodiments, the indole compound is at least about 25% (such as at least about any of 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%) more specific to adipocytes than to muscle cells (such as skeletal muscle cells).

Second Therapeutic Agents

The present disclosure provides compositions that can be co-formulated, co-administered, and/or co-marketed with a second therapeutic agent. In some embodiments, the second therapeutic agent is co-formulated with an indole compound and administered simultaneously with the indole compound. In some embodiments, the second therapeutic agent is administered prior to or after the administration of an indole compound. The second therapeutic agent can be administered locally, regionally, or systemically.

In some embodiments, the second therapeutic agent is a detergent, a bile acid, bile salt, deoxycholic acid or a salt thereof. In some embodiments, the second therapeutic agent is phosphatidylcholine or deoxycholate or mixtures thereof. These compositions are described in US 2005/0267080, WO 2008/066775 and US 2009/0233885, which are herein incorporated by reference in their entireties.

EXAMPLES

The following examples are offered to illustrate but not to limit the invention.

Example 1

The time and concentration dependent effects of drug substance on both cell viability and toxicity were evaluated using a two-color fluorescence assay that measures plasma membrane integrity and intracellular enzyme activity. Live cells are determined by the strong fluorescence of calcein AM upon enzymatic conversion. In contrast, ethidium bromide signal is dramatically increased upon entering a cell with damaged membranes and binding to nucleic acids. The ratio of ethidium to calcein fluorescence is an excellent measure of the relative amount of live and dead cells.

Test compounds are commercially available. Test compounds include compounds from Table 1. Comparative non-indole compounds were also tested: C-8, C-19, C-20, C21, C-56, C-57, C-58, C-60, and C-61. Positive controls include 1% sodium deoxycholate (DC) (MasterPharm, Richmond Hill, N.Y.), phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ml (MasterPharm, Richmond Hill, N.Y.), PC 50/DC24 (Network Lipolysis, Drensteinfurt, Germany) and Aqualyx®, a sodium deoxycholate in a lactose carrier. Compound 44H is a high concentration version of Compound 44.

The effects of various test compounds were compared to currently available known cytotoxic compounds (positive controls) including Aqualyx, deoxycholic acid (DC), and the two combinations of phosphatidylcholine and deoxycholic acid (PC/DC) on cell viability and toxicity. Saline was used as a negative control. All compounds were incubated with approximately 1-2 million cells/ml for varying amounts of time to induce cell death and/or disrupt membrane integrity. The compounds tested showed a gradient of adipocyte killing behavior as a function of time ranging from very aggressive to modest cell death (FIGS. 1 and 2). FIG. 1 suggests that there are multiple compounds that have more aggressive, intermediate, and less aggressive cell killing behavior as compared to the positive controls Aqualyx, DC, and PC/DC (FIGS. 1 and 2).

In a separate study, the influence of both test compound concentration and incubation time on cell viability and cytotoxicity of adipocytes was evaluated (FIGS. 3 and 4). FIGS. 3 and 4 shown that increasing test compound concentration generally increases the ethidium bromide signal (cell death). Similar to the previous time dependent study, an initial increase in cell death followed by a plateau and a diverse range of test compound activity from aggressive to non-aggressive cell cytotoxicity was observed.

Example 2

Indole compounds were tested in immediate ex-vivo tissue. Test compounds include a negative control (saline) which shows no response, or normal adipocyte architecture. In all specimens, some shearing (linear tears) and compression artifacts (rectangular fat cells rather than round) were present, as fatty tissue is notoriously difficult to keep from fragmenting during histologic processing. In order to prevent interpretation errors, the treatment zone located in the center of the specimen was evaluated from the dermal/fat junction distally, and only if adjacent to a section of normal appearing fat.

Test compounds included indole compounds in Table 1. Compounds to be tested for tissue preference were first screened for adipocyte cytoxicity in order to qualify. In addition to normal saline and compound diluent (DMSO plus PBS) (negative controls), positive controls include 1% sodium deoxycholate (MasterPharm, Richmond Hill, N.Y.), phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ml (MasterPharm, Richmond Hill, N.Y.), PC 50/DC24 (Network Lipolysis, Drensteinfurt, Germany) and Aqualyx®, a sodium deoxycholate in a lactose carrier (Marllor International, Italy).

Initial screening was performed using a variety of cell viability and cytotoxicity assays, including Presto Blue® (Invitrogen, Grand Island, N.Y.), Alamar Blue® (Invitrogen, Grand Island, N.Y.), Cyto-Tox One® (Promega, Madison, Wis.), and Cell Titer Glo® (Promega, Madison, Wis.). Due to reaction of several test compounds with the blue dye, the redox assays were discontinued. An MTT terazolium assay was performed, as well as LDH and ATP based assays. It was determined that the most consistency occurred with the dual function assays, Multi-Tox Fluor® (Promega, Madison, Wis.) and LIVE/DEAD® for mammalian cells (Invitrogen, Grand Island, N.Y.). The LIVE/DEAD® for mammalian cells assay was used. LIVE/DEAD® for mammalian cells assay is a calcein (live read)/ethidium bromide (dead) multiplex assay.

There was a wide range of tissue preference ranging from none—all compounds were indiscriminately cytotoxic—to about 90%. Indole (Compound 33) was fairly tissue preferential at about 53-56%. Ethidium results for indole for dermis, muscle, and endothelial cells showed that indole was less than half toxic for those cells than for adipocytes at 4 time points over 24 hours. FIG. 5 shows results for test compounds for adipocytes, dermis, muscle, and endothelial cells for Compound A (Aqualyx®) and Compounds 2, 29, 40, 41, and 43.

As shown in FIG. 5, the most strongly tissue preferential group included six tested compounds, Compounds 2 and 43 in the aggressive category, Compounds 40 and 41 in the moderate range, and Compounds 29 in the less aggressive range. (Compound 10 is not shown in FIG. 5.) These compounds had adipocyte cytotoxicity numbers that are 3 to 4 times stronger than those noted with other tissue types. Additional data for tissue specificity results are shown in the table below.

In general, the PC/DC compositions were indiscriminate. Aqualyx® had slight tissue specificity toward nerve tissue and endothelial tissue. The deoxycholate composition was indiscriminate.

FIG. 6 shows results for test compounds for adipocytes, dermis, and muscle cells for Compound B (saline control) and Compounds 1, 2, 3, 4, 5, and 10. All the bars in FIG. 6 indicate kill rate (ethidium). In the compound number, “a” refers to compound tissue preference at 2 hours. In the compound number, “b” refers to compound tissue preference at 5 hours.

As shown in FIG. 6, Compounds 2 and 10 were the most aggressive in this group of compounds. Compound 4 was less aggressive, but shows specificity for adipocyte killing. Compound 1 showed no preference for cells over time. Compound 5 showed more nerve preservation, but a late dermal spike appeared.

FIG. 7 shows results for test compounds for adipocytes, dermis, and muscle cells for Compound C (saline control), Compounds D and E (deoxycholate), and Compounds 29, 7, 33, 38, and 40. All the bars in FIG. 7 indicate kill rate (ethidium). In the compound number, “a” refers to compound tissue preference at 2 hours. In the compound number, “b” refers to compound tissue preference at 5 hours.

In FIG. 7, Compound C is a saline control; Compound D is phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ml; and Compound E is phosphatidylcholine 25 mg/ml plus deoxycholate 24 mg/ml. Both of Compounds D and E are detergents that showed no tissue specificity. Recent reports following clinical trials of 1% deoxycholate show two instances of facial nerve palsy and numbness with paresthesias in up to 40% of patients treated. Compounds D and E are toxic to nerve and dermal fibroblasts as they are to adipocytes.

As shown in FIG. 7, Compound 29 is strongly adipocyte preferential, while the adipocyte kill rate is equivalent to that of Compounds D and E. Compound 7 showed not tissue preference. Compound 33 showed definite tissue specificity at two time points. While the specificity is not as strong as other compounds tested, there is much more tissue specificity than with Compounds D and E. Compound 38 was an aggressive adipocyte killer and is also toxic to nerve cells, although not nearly as toxic to dermal fibroblasts. Compound 40 showed tissue specificity at two time points. In FIG. 7, Compounds 29 and 40 showed the most specificity for adipocyte killing among the compounds tested in this group. Compound 33 showed moderate tissue specificity, but a fairly low adipocyte kill rate.

FIG. 8 shows results for test compounds for adipocytes, dermis, and muscle cells for Compound F (saline control), Compounds G (Aqualyx®), and Compounds 41, 43, and 44. All the bars in FIG. 8 indicate kill rate (ethidium). In the compound number, “a” refers to compound tissue preference at 2 hours. In the compound number, “b” refers to compound tissue preference at 5 hours.

In FIG. 8, Compound F is a saline control; Compound G is Aqualyx®. Compound G showed no tissue specificity. Compounds H and I are diluent controls, which include cells and DMSO/PBS. CellDMpb is a diluent having DMSO and PBS and cells.

As shown in FIG. 8, Compound 41 had a high tissue preference index and strong adipocytolytic capability. Compound 41 is not as aggressive as Compounds 2, 38, or 43. Compound 43 is adipolytic, yet has a low kill rate for nerve cells and dermis. It is a more aggressive than Compound 41. Compound 41 would be effective in areas where there is a large fat deposit. Compound 44 is not as specific as the other compounds tested in this group.

The following table shows tissue specificity results for the tested compounds. A sample of DMSO/PBS was a negative control. A sample of Aqualyx® was a positive control. In the table, 24M is phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ and 25N is C 50/DC24; these were positive controls. The numbers in the table refer to averaged ethidium numbers. The percentages represent the relative kill rate for each cell type when rated against the adipocyte kill rate for that compound. All tissue types were tested on the same plate against adipocytes in order to standardize results.

Compounds 28, 91 and 94 showed high kill rate for adipocytes and high specificity for adipocytes over nerve cells, dermal cells, muscle cells, and endothelial cells. Compounds 78, 2, 27, and 40 showed high specificity for adipocytes over nerve cells, dermal cells, muscle cells, and endothelial cells. Compounds 5, 4, 30, 33, and 44 showed about 50% preferential for adipocytes over nerve cells, dermal cells, muscle cells, and endothelial cells. Compounds 3 and 38 showed moderate preference of adipocytes over nerve cells, dermal cells, muscle cells, and endothelial cells.

Example 3

As the indole group has not been previously used for intralesional fat reduction, a method of obtaining histologic specimens had to be modified. In 1978, May et al (Plast. Reconstr. Sug. 1978 February; 61(2): 256-67) noted that segments of human tissue remained viable and could be reattached to the body using microvascular techniques for up to 12 hours after separation. After 12 hours, a phenomenon called “no-reflow” occurred, and the tissue was no longer viable.

The tissue model described herein, therefore, was immediate ex-vivo abdominoplasty tissue that had been permitted for use by the surgical patient. Segments of abdominal skin and subcutaneous fat were injected with identified test compounds, plus a negative saline control and three positive controls: 1% deoxycholate, the commercial preparation of Aqualyx®, and the Network Lipolysis PC/DC formula.

In compounds that were identified and confirmed as adipolytic using three separate sessions of the Live/Dead cell viability assay (Invitrogen), specimens were injected and then placed into formalin at 1 hour, 4 hours, and 12 hours. Because there was no host; inflammatory changes would not be expected. This study was only performed to assess the immediacy of adipocyte changes, and to determine the method of action of each compound.

As a whole, the compounds of the embodiments appear to have a pyroptotic mechanism of action. Pyroptosis is a relatively new category of cell death mechanism. While apoptosis is programmed cell death and by definition, there is no inflammation, cytolysis causes cell membrane rupture followed by an immediate onset of swelling and inflammation in the affected area. Pyroptosis is defined as a combination of these two mechanisms, in which some cells die as a programmed function, and some cells die due to mitochondrial dysfunction or cell wall lysis or both. Pyroptosis is the central continuum between apoptosis and cell wall lysis, with some clinical and microscopic manifestations of both.

FIG. 9A shows a saline control with adipocytes intact.

FIG. 9B shows a histology test sample with 1% deoxycholate at 4 hours. Cell wall lysis with a large area of “missing” tissue is present. The central oblique line of injection shows significant cell damage while normal fat can be seen at the periphery, in the lower left and upper right corners. This is a classic appearance, showing the limited dispersion of the deoxycholate compound.

FIG. 9C shows a histology test sample with PC50/DC 24 at 12 hours. Minor apoptotic changes such as pyknotic nuclei and “ghosting” can be seen. No cell wall lysis is present.

FIG. 9D shows a histology test sample with Compound 88 at 4 hours. The appearance is very similar to that of PC/DC. Pyknotic nuceli are present. Both ghosting and quite shrunken cells are noted with folding of the cytoplasmic membrane. This is an example of a compound with similar efficacy as PC/DC, with a primarily apoptotic mechanism of action.

FIG. 9E shows a histology test sample with Compound 41 at twelve hours. Pyroptotic mechanism is well demonstrated here. Two areas of cytolysis are shown using dark arrows. Pyknotic nuclei are strongly present, as are ghosting and shrunken intact cells.

FIG. 9F shows a histology test sample with Compound 38 at four hours. The mechanism of action of this compound is primarily cytolysis, as seen by fragmentation of multiple cell walls, and empty area where adipocytes used to be. Some signs of apoptosis are present. In some embodiments, it is difficult to assign an exclusively cytolytic or apoptotic mechanism, as both are most commonly seen.

FIG. 9G shows a histology test sample with Compound 2 at 1 hour. This compound is aggressive, and cases more cytolysis than apoptosis.

FIG. 9H shows a histology test sample with Compound 29 at 12 hours. This compound exhibits primarily an apoptotic mechanism.

FIG. 9I shows a histology test sample with Compound 33 at 4 hours. Indole, the parent compound, shows pyroptotic activity when injected into adipose tissue. A tattoo marking the injection site is seen in the upper left margin. Dark arrows show regions of cytolysis. Ghosting of apoptotic cells is also visible.

In summary, the compounds of the embodiments have a variety of effects on adipocytes, with some compounds inducing more programmed cell death, and some more aggressive compounds primarily working by lysing cell membranes the majority of compounds are pyroptotic; evidence of both mechanisms of cell death is seen.

Example 4

The diagram in FIG. 10 shows an injection pattern for basic level users of an injectable lipolytic composition. This pattern presupposes some dispersion of the injectable composition. In the facial region, a grid or ruler was used to measure the distance between injection points.

In Palmer and Duncan's article on the standard of practice for injection lipolysis (Duncan D I, Palmer M: Fat reduction using phosphatidylcholine/sodium deoxycholate injections: standard of practice. Aesthetic Plast. Surg. 2008; 32: 858-72), these points were described as being 1 cm apart for facial regions, and 1.5 cm apart in body regions. Facial injections should be performed with a meso needle that is 6 mm long, in order to standardize the depth of injection. A dose of 0.2 to 0.4 cc of a 10 mg/ml product is the standard dose per pre-marked injection site in facial regions. In body regions, a dose of 0.4 to 0.5 cc of the same concentration would be used, and the grid pattern would show injection points 1.5 cm apart.

An alternative pattern would be a multi-level injection, using an under-the-skin type delivery. These would be performed from a single entry site, and would be executed in a ray-type distribution, similar to liposuction. The value of treating multiple levels of adiposity has been recently shown, so a better and more uniform response can be obtained with this method. Also, drugs with poor dispersion can be better delivered to the target tissue this way.

Example 5

This example reports exemplary compounds reported in Example 1. Over seventy compounds of the embodiments were tested for adipocytolysis, then for tissue preference. A consistent assay with multiplex information was a calcein/ethidium bromide assay that assesses cell viability and cell death simultaneously. Cell viability was checked using the Countess device. All plates were inoculated with 100 microliters of the appropriate cell types. A 6 well repeat was used to verify results. Cell types used included cultured human adult derived adipocytes, dermal fibroblasts, skeletal muscle cells, and endothelial cells (Cell Applications, Inc., San Diego, Calif.). Human peripheral nerve cells (Innoprot, Spain) were also used.

Compounds were formulated using a DMSO/PBS excipient. A 10 mg/ml concentration was used. One hundred microliters of test compound was inserted into 6 wells of 5 cell types, placed in adjacent rows. The plates were incubated for 4 hours. Indicator was added to each well, and plates were read at 45 minutes using a fluorescence spectrophotometer (Molecular Devices, Sunnyvale, Calif.).

FIG. 11 shows results for adipocytes, dermal cells, nerve cells, muscle cells, and endothelial cells for control compounds. Normal saline was a negative control. Excipient was DMSO/PBS excipient. Positive controls included phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ml (PC/DC, MasterPharm, Richmond Hill, N.Y.), and Aqualyx®, a sodium deoxycholate in a lactose carrier (Marllor International, Italy). All the bars in FIG. 11 indicate kill rate (ethidium). The tissue preference assays in FIG. 11 were repeated three times, one month apart, to verify consistent findings. As shown in FIG. 11, the control compounds were indiscriminate for adipocytes, dermal cells, nerve cells, muscle cells, and endothelial cells.

FIG. 12 shows results for adipocytes, dermal cells, nerve cells, muscle cells, and endothelial cells for control compounds and test compounds. All the bars in FIG. 12 indicate kill rate (ethidium). As shown in FIG. 12, Compounds A, B, C, D, and E showed high specificity for adipocytes over dermal cells, nerve cells, muscle cells, and endothelial cells. PC/DC shows uniform cell death with all tissue types. The parent indole compound (Compound 33) showed about 50% tissue preference.

FIG. 13 shows results for adipocytes, dermal cells, nerve cells, muscle cells, and endothelial cells for control compounds and test compounds. All the bars in FIG. 13 indicate kill rate (ethidium). As shown in FIG. 13, Compounds F, G, H, I, and J showed high specificity for adipocytes over dermal cells, nerve cells, muscle cells, and endothelial cells. There was no tissue preference for either control (saline and Aqualyx®).

Example 6

This example reports exemplary compounds reported in Example 1. A mouse study was performed to test compounds of the embodiments. Eight test compounds were injected. In addition to normal saline and compound diluent (DMSO plus excipients) (negative controls), positive controls included 1% sodium deoxycholate (DC, MasterPharm, Richmond Hill, N.Y.), phosphatidylcholine 25 mg/ml plus deoxycholate 12 mg/ml (PC/DC, PC25/DC12, MasterPharm, Richmond Hill, N.Y.), and Aqualyx®, a sodium deoxycholate in a lactose carrier (Marllor International, Italy).

Seventy nude mice were chosen for a study of safety and efficacy of injectable lipolytic compounds. Human fat was harvested one hour prior to the injection procedure. 0.5 cc of fat was loaded into micro syringes. Engraftment took place under general anesthesia. Four weeks later, the fat pad size was measured and compounds injected precisely using a 6 mm meso needle in the center and 0.5 cm cephalad and caudad to the midpoint. Mice were sacrificed at one day, one week, two weeks and 4 weeks. One mouse died following injection. This same mouse exhibited SRP (sick rodent posture) following engraftment. Three mice developed SRP and were euthanized according to protocol.

Each fat pad was measured and weighed on the analytical balance at the time of sacrifice. Photos were taken and histology was performed. SEM was performed at two weeks and 4 weeks. Gross characteristics of the fat were documented.

At four weeks, clinical size reduction was just becoming visible with PC/DC and DC injectables. Visible and measurable fat reduction was noted with DC and three test compounds, although the number of mice with each compound sacrificed at 4 weeks could not give any statistically significant numbers. The two compounds that induced death or SRP were deleted, as clinical performance for either was not strong.

Details of injection of compounds into the mice and results are discussed below. Each mouse was given general anesthesia. Previous to injection of compounds, the fat pad was remeasured as not all fat takes as a graft. Mean graft take was 68%.

Size reduction after compound injection was measured against the measurement taken just previous to injection of compounds. The fat grafts migrated laterally in all but one case. Compound dose was calculated based on the average weight of each mouse and was based on the maximum safe dose of PC/DC. At 0.4 mg/gram, maximum dose was estimated to be 10 mg. Actual dose was 6 mg per mouse.

Three injections were performed and were perpendicularly given to a depth of 0.6 cm using a 30 gauge meso needle, spaced 0.5 cm apart. Eight test compounds were injected. Negative control was saline and the DMSO excipient. Two positive controls, Aqualyx® and PC25/DC12, were injected. Five mice exhibited small excoriations at the injection site. All had disappeared within one day.

Mice were given a special antibiotic diet. No mouse became infected. After the first 24 hours, all recovered well and seemed to ignore the fat pads. Sacrifice of mice took place as schedule. A limited postmortem at 24 hours showed no apparent systemic effects.

FIG. 14 shows a sample mouse at one day postinjection. No effect from the compound was noted. Neovascularization of the graft was visible beneath the thin skin of this mouse. No effect on adjacent tissue nor vital organs was noted.

FIG. 15 shows a mouse, injected with Compound B, which had a lobulated graft. The most cephalad pad was not injected. The central pad was injected with 0.1 cc or 1 mg of compound. The most caudal fat pad was injected with 0.2 cc or 2 mg of compound. As early as one week, fat necrosis had been induced with Compound B. FIG. 15 shows that fat necrosis occurred prevalently on the most caudal pad and to a lesser degree on the central pad.

FIG. 16 shows deoxycholate injected fat pad at Day 1. Immediate necrosis was apparent in the injected segment. The lack of dispersion was made clear in this specimen.

FIG. 17 shows gross appearance of Compound D (above) as compared to excipient control (below), at one week postinjection. Tested compounds of the embodiments appeared to induce some type of fat reaction. Visible gross changes included discoloration as early as one week. Some liquefaction was seen at two weeks. A soft granular appearance with size reduction was noted at 4 weeks.

FIG. 18 shows a mouse at one week postinjection. The mouse was treated with Compound H. There was discoloration and textural changes in the fat pad after injection of Compound H, as shown in FIG. 18.

FIG. 19 shows the effect of Compound I at two weeks. There is some liquefaction and textural change. Definite fat necrosis was present. FIG. 20 shows the effect of Compound I at four weeks. Dispersion was good; the entire fat pad was been affected. A measured 33% reduction in fat pad size was noted. Compound I showed good results and is an excellent test compound in this study.

FIG. 21 shows PC/DC treated fat pad at 4 weeks. There was almost no visible change from its original condition.

A clinical outcome view was taken to test compounds for fat killing potential. A final arbiter of success is visible reduction in the size of the fat pad following treatment. This endpoint is best observed by clinicians.

Example 7

Scanning electron microscopy (SEM) can provide images of a sample's topography and composition. SEM was performed on various adipose cells.

This example reports exemplary compounds reported in Example 1.

FIG. 22 shows the appearance of normal fat cells with saline control. There was a very thin, fibrous “netting” that holds the cells together. As shown in FIG. 23, the fibrous scar response generated by deoxycholate was massive. There are very few live cells left in this tissue segment; most was fibrous scar response. An ideal response would be either an apoptotic response with little inflammation in cases where only fat reduction is needed, or a combination of fat reduction and moderate inflammation when tissue tightening is the desired response. The compounds of the embodiments can generate these desired responses.

FIG. 24 shows SEM of an untreated cultured adipocyte. The physical characteristics of adipose cells were easily identified when cultured cells are treated. Intact adipocytes were round, with a mean diameter of about 100 microns. There was great variability in the size of adipocytes, which can range from 30 microns to over 200 microns. The surface of the cell membrane was not slick and smooth. FIG. 25 shows intact adipocytes in vivo. These were not perfectly round. Their shape was affected by its neighbors.

FIG. 26 shows SEM of cultured adipocytes treated with PC/DC at four hours. There was blebbing, a hallmark of apoptosis. Bleb is an irregular bulge in the plasma membrane of a cell. Cell wall injuries can have two outcomes. If a large enough defect is created, the cell cannot repair itself and it undergoes necrosis, with the creation of lysozymes and egress of the cell contents. Clinically, this will result in swelling and inflammation of the treatment region. Smaller blebs may cause poration, which can induce programmed cell death.

FIG. 27 shows cultured adipocytes treated with PC/DC in vivo at 4 weeks.

Blebbing was a prominent feature. Inflammation was denoted by the formation of a fibrous coating of the cells.

FIG. 28 shows the effect of deoxycholate on a single cultured adipocyte after four hour incubation. The cell membrane has been disrupted at multiple sites.

FIG. 29 shows a barren landscape of tissue treated with deoxycholate at 4 weeks. There were very few living adipocytes. Fibrous ingrowth was extensive. These SEM findings correlated with the histology seen in deoxycholate treated tissue. The inflammatory reaction was intense; all cells within millimeters of the treatment region died an acute necrotic death. This led to extensive scarring such that the “soft” tissue is no longer soft.

Majno's description of the process of adipocyte cell death is either apoptosis or necrosis. (Majno et al., “Apoptosis, oncosis, and necrosis. An overview of cell death,” Am J. Pathol. 1995 January; 146(1): 3-15.) FIGS. 30-31 shows diagrams of a mechanism of action of Majno.

The mechanism of action of injected sodium deoxycholate, is the causation of immediate cell necrosis in adipoctytes localized to a narrow radius of the injection. Phosphatidylcholine/deoxycholate (PC/DC) was much slower to act. PC/DC induced early apoptosis followed by a gradual, more diffuse induction of cell lysis over a period of 4 to 6 weeks.

However, the compounds of embodiments can be shown to follow a different mechanism of action. The mechanism of action includes poration and effusion. The mechanism of action of lipolytic indole compounds is a new one called chemoporation. SEM micrographs of the mechanism are shown in FIGS. 37-41. A compound of the embodiments was injected into the subcutaneous fat using either a depot or ray type serially repeated pattern. No cell necrosis took place. As the compounds of the embodiments are tissue preferential, no other tissues are affected. The reason no other tissues were affected is because this mechanism of action works for fat cells only. An initial response, seen as early as four hours post-treatment, was poration of the treated cells. Tiny openings in the adipocyte membrane became more prominent, and the cell wall surface began to appear “holey.” (FIG. 37) Then, for example, hundreds, then thousands of lipid droplets collected immediately under the cell membrane. As other cells do not have intracellular lipid droplets, this mechanism does not affect them. (FIG. 38) As the pores became larger, lipid droplets diffused through the cell membrane and became extracellular. (FIG. 39) With time, thousands of lipid droplets collected on the surface of the cell wall. (FIG. 40) There was visible “crumpling” or loss of internal cell volume. (FIG. 41) Once a critical loss of volume occurred, the cell died. The steps in this process following drug injection or other type of application included poration, lipid droplet formation and collection just under the cell wall, diffusion through the cell membrane, exteriorization, and cell implosion with subsequent death.

FIGS. 32-36 below show examples of a mechanism of action with SEM of poration and effusion. FIGS. 37-41 below show examples of a mechanism of action with SEM of poration and effusion in close-up views.

FIG. 32 shows the effect of Compound A on adipocytes in vivo at 4 weeks posttreatment. The cells underwent a process of lipolysis in which thousands of lipid droplets coalesce just under the cell membrane. Poration occurred, and the lipid droplets escaped. When cell volume depletion becomes critical, the cell signals its own death.

FIG. 33 shows poration of a cultured adipocyte caused by Compound B.

FIG. 34 shows the effect of Compound B at 4 weeks. There were platelets on cell at the lower right. Compound B elicited a vascular response, with platelets and white blood cells (WBCs) within the treatment region. There was also a lack of extensive scarring.

FIG. 35 shows severe spongiform poration of an isolated cultured adipocyte after a 4 hour exposure to Compound C. This type of pyroptotic cell death caused less inflammation than deoxycholate's necrotic process.

FIG. 36 show a negative control with the effect of DMSO excipient at 4 weeks. There were cells that appear intact with slight fibrous adhesions.

As discussed above, FIGS. 37-41 show examples of a mechanism of action with an SEM of poration and effusion in close-up views. FIG. 37 shows SEM with a close-up view of poration of an adipocyte. FIG. 38 shows a collection of lipid droplets underneath the cell membrane. FIG. 39 shows an SEM with a close-up view of effusion of an adipocyte. This was a single cell. There were lipid droplets coming out of the pores. FIG. 40 shows a close-up view of a cell treated with Compound J at four weeks. There was extrusion of thousands of lipid droplets. FIG. 41 shows a close-up view of adipocyte death. With the tested compounds of the embodiments, the gradual process over a four week period took longer than deoxycholate's reaction, which was instantaneous. The tested compounds of the embodiments worked more quickly than PC/DC. Tissue treated with PC/DC was just beginning to react at four weeks.

FIGS. 42-45 show comparison of the effect of Compound J with control compounds. FIG. 42 shows tissue injected with saline at four weeks. Cell sizes vary. The fibroseptal network is apparent. FIG. 43 shows SEM of tissue treated with PC/DC at four weeks. There is a blebbing mild fibrous reaction. The cells are still intact. FIG. 44 shows tissue treated with deoxycholate at four weeks. Massive fibrous replacement of normal tissue is apparent. FIG. 45 shows tissue treated with Compound J at four weeks. There are lipid droplets and a single lysed cell. Fibrous response with Compound J is modest.

FIGS. 46-50 show the effects of tested compounds. FIG. 46 shows the effect of Compound D at 4 weeks following injection into human fat. This effect was similar to, but more profound than the effect of PC/DC. There was collapse of cell volume with round exteriorized lipid droplets. There were also lumpy shapes just under the cell membrane. These were hundreds of lipid droplets waiting to escape.

FIG. 47 shows the effect of Compound E in vivo after 4 weeks. There are extracellular lipid droplets, and folding of a dying adipocyte. A disrupted cell is noted in the lower right of the figure. Some fibrous response is noted.

FIG. 48 shows tissue treated with Compound I at 4 weeks. There were lipid droplets that have discharged through the cell wall. This mechanism was characteristic of the compounds of the embodiments.

FIG. 49 shows the effect of Compound H at four weeks. There were crumpled cells, exteriorized lipid droplets, and more fibrous response than other tested compounds.

FIG. 50 shows the effect on cultured cells that were treated with Compound I for four hours. Compound I induced an array of response including some cell lysis.

As shown in the figures, the steps in the adipocyte killing process appeared to be initial poration followed by collection of the lipid droplets under the cell membrane. The small pores became larger, and the lipid droplets underwent effusion. The cells lost volume and looked crumpled. Once a critical mass of volume was lost, cell signaling induced death.
